The WIBS-5 is the world’s only instrument for real-time, single particle measurement of atmospheric bacteria, molds, pollen, and other bioaerosols. WIBS-5 measures fluorescence to infer the presence of biological material in particles and provides detailed data on size, relative measure of shape, and fluorescent properties to enable classification of pollen, bacteria, and fungi.

Measure trace amounts of mold and other bioaerosols in the atmosphere. Get an instrument optimized for detection of bioaerosols, tryptophan, and NADH using two excitation wavelengths and two emission bands.  Specific data for particles from 0.5 to 30 µm, as well as particle time-of-flight to detect coincidence; configurable to measure larger particles such as pollens and fungal spores.

Enables selection of filter criteria for both full and partial measurements. Filter data using a wide variety of criteria: particle size, asymmetry, and concentration; fluorescent excitation and emission; or ratios of any of these parameters.  Measure particles in real time and see housekeeping parameters to monitor instrument health and enhance operational uptime.

WIBS-5 Software

Two software packages are available for the WIBS-5: the standard software system and the WIBS Data Analysis Toolkit.

Standard Software

The WIBS-5 graphical user interface features several components. The main window shown below details measured particles in real time and gives information on several housekeeping parameters.

The WIBS toolkit allows for loading, processing, and inspection of data generated by the WIBS-5/NEO. The toolkit’s functionality includes the following:

  • Loading single and multiple raw data files containing particle-by-particle fluorescence, size, asymmetry factor, and other data
  • Converting particle-by-particle data into time-resolved particle concentrations and size distributions
  • Basic plotting capability
